How to Adjust Brightness in Windows 10

Adjusting your screen brightness in Windows 10 can improve visibility and reduce eye strain. Follow these steps to change your screen’s brightness settings.

Step 1: Open Settings

Click on the Start button and select the gear icon to open the Settings menu.

Once you click the gear icon, the Settings menu will appear. This menu is like your control center for various system settings, including brightness.

Step 2: Go to System

Within Settings, click on the ‘System’ option.

‘System’ is where you can manage all your display settings. It’s the go-to place for anything related to your screen, from brightness to resolution.

Step 3: Click on Display

Under the System menu, select ‘Display’ on the left sidebar.

The Display settings will appear, showing options to adjust your screen’s brightness and other related settings.

Step 4: Adjust the Brightness Slider

Find the ‘Brightness and color’ section and move the brightness slider left or right to adjust the brightness.

Sliding to the left will reduce the brightness, making the screen darker, which is useful in low-light conditions. Sliding to the right will increase the brightness, making the screen brighter for well-lit environments.

Step 5: Save and Exit

After adjusting the slider to your preferred brightness level, simply close the Settings window.

Windows 10 automatically saves your changes, so there’s no need to click a save button. Just exit the Settings window, and you’re done!

After you complete these steps, your screen brightness will be adjusted to your preference. This change happens instantly and will be applied until you decide to adjust it again.
